SPRING BED-BOTTOM.

SPECIFICATION forming art of Letters Patent No. 274,823, dated March 27, 1883.

Application filed February 24, 1883.

ing drawings, and to the letters of reference fication.

. This invention relates to spring bed-bottoms, and it is an improvement on a bed-bottom for which I have made an application, filed December 26, 1882, and patented January 30, 1883, No. 271,517. The object of this invention is to simplify and cheapen the construction of bed-bottoms, and at the same time provide a spring-bottom which shall afford comfort and be durable in use.

The principal feature of the invention consists in the combination of elliptical wire springs united to slats and connected to each other in rows by a broad flat metallic or wooden strip or wire. i

The accompanying drawings illustrate my invention.

Figure l is a plan view of the bottom. Fig.

.2 is a section through a portion of the slats,

showingthe wire springs in elevation. Fig.

. 3 is an enlarged view of a semi-elliptical wire united by hinges at other points, if desired. The wires 0, forming the springs, are bent in to the form of a nearly complete ellipse, and

have their endsf, for an inch more or less in length, bent outward at right angles and inserted into sockets or holes a, bored in the wooden slats A,- near their edges. As shown in the drawings, each row of wire springs is supported on two slats properly spaced apart. Therows of springs being in position in the slats, they are connected at the top by broad flat bands or strips 1), tied by a small wire loopor staple to each wire spring, for the pur pose of better sustaining the springs in proper relation to each other, and for protecting the mattress from the wear of the wires. It is preferable to set the wires 0 into the slats, so that those of adjoining rows break joints with each other-that is, so that the wires of one row shall be secured in the slat in the interspacebetween the wires of the next row of wires, as shown in the drawings. Ofcourse the wire springs, properly secured. to the slats, could be used without the flat connectingbands D.

Havin g described my invention what Iclaim, and desire to secure by Letters Patent, is-

1. The improved bed-bottom consisting of the combination of the slats A and the connecting elliptical wire springs O, secured to the slats in the manner shown, as described.

2. The elliptical wire springs G, having-bent endsf, in combination with the slats A, having the sockets a, connected together as described, to form a bed-bottom.

3. The slats and theconnecting wire springs, constructed as described, in combination with the wire ties or broad bands D, connecting 'the springs at the top, for the purpose described.

ln testimony that I claim the foregoing as my owninvention Iaffix my signature in presence of two witnesses.
